RadioMaster TX16S MK3 MAX - Gemini ExpressLRS Radio

The 2026 UK flying season is here, and while the CAA is busy updating Article 16 for the seventh time, RadioMaster has been busy making your current radio look like a Victorian relic. The RadioMaster TX16S MK3 MAX isn't just a controller; it's a high-performance FPV drone transmitter powered by the beefy STM32 H7 chip—because apparently, your radio needs more processing power than the Apollo 11 lander just to tell a quad to "go up." With built-in Gemini dual-band ExpressLRS (2.4GHz and 900MHz), you'll have a link so stable it could survive a 2026-level chip shortage or a direct hit from a "Flying Cat" drone. We’re selling this because we like money, but you’re buying it because "that’ll buff out" hasn't applied to your last three fails.

Why You Want It

You want it because those buttery-smooth AG02 CNC Hall gimbals make your shaky split-S look like a cinematic masterpiece (or at least hide the fact you haven't practiced in weeks). This isn't the standard MK3; the MAX edition adds a carbon-fibre finish and enough CNC aluminium to make a machinist weep with joy. It’s got a 5-inch touchscreen that’s actually sunlight-readable, so you can see exactly which setting you’ve messed up while standing in a rainy field in Derbyshire. We've even added a built-in motion sensor—now you can trigger telemetry callouts by tilting your radio like a lunatic.

Specifications

• Processor: STM32 H7 (Processing power for days, or at least until the next firmware update)
• RF System: Dual-band Gemini 2.4GHz & Sub-G 900MHz (Redundancy for the paranoid pilot)
• Gimbals: AG02 Quad-Bearing CNC Aluminum Hall (Friction is so 2025)
• Display: 5-inch 800 x 480 IPS Touchscreen (Vivid enough to distract you from your drift)
• Cooling: High-output fans & Alum. heat sink (Keep your cool when the 1W module heats up)
• Storage: 4GB Internal Flash + MicroSD slot (Store all the memes and zero flight logs)
• Battery Circuit: Smart Balance charging (Because 18650s deserve a long, happy life)
• Weight: 864g (Strong forearms lead to better loops, probably)

Key Features and Highlights

• Dual Foldable Antennas — High gain for long-range, compact for when you inevitably throw it in your bag in a huff.
